3060 Ti allergic to some displays..?

[Macro Device]

My homie got himself a brand new PC which passes all tests, runs all benchmarks and works without any hint of instability but seems to deem some monitors not worth working with.

One of said monitors is a Benq G2400W. Another is some TV I have no specs on.

What I know of his PC configuration:

ASUS TUF Gaming B660M-Plus D4 (BIOS 1620)
i5-12600KF (might be old stepping, might be new stepping, no idea)
2 sticks of 16 GB each with some XMP profile (no idea about the details)
Zotac RTX 3060 Ti Twin Edge
Not sure if any other component is relevant here.

Everything is being connected via HDMI. Some displays just work and some displays, whilst working totally fine with other devices like XBOX and PS4, totally refuse to show anything connected to his PC. We already tried many HDMI cables, both 2.x and legacy models.

Why does that happen and how do we fix it? I suggested buying a new monitor because his TV and his G2400W are quite frankly too out of loop already. But is there a way to make them work with this system?

Possible the devices being old use a HDMI standard that is outdated and won't see the GPU regardless of the cable.

Yeah HDMI compatibility stuff. My old Sony TV doesn't work with modern GPUs.

This is literally impossible, HDMI is backwards-compatible. I guarantee you it is the cables, it is always the cables.

I don't know what to tell you. I haven't gotten that TV to work with modern GPUs but it works with old laptops and a Chromecast. I've tried different cables. As for it being literally impossible, I've seen a NIC not work with a specific switch...

Unless you need HDMI 2.0 for high refresh gaming monitor, get a passive DP to HDMI adapter and see how it does with monitors that aren't getting detected directly.
If it's not cable, it's usually EDID/handshake being funky.
Putting something in-between "two idiots that can't talk to each other despite being in the same room" - should help, assuming that's your issue.

Told'im, now we wait. Not sure if he'll buy it this weekend, Poland ain't famous for stores working on Sundays.
